Unfortunately, i dont speak Italian.
The reason that the Windows 2008 worked, is due to the fact that there is the Intel Matrix F6 drivers already embedded in the Windows.
So far, i tried nearly all OS on this board and it worked fine. I installed Windows 2003 (32 bit and 64 bit) and Windows XP (32 bit and 64 bit) in RAID Mode without any problem.
Bios: Configure SATA as RAID and Intel Matrix (not LSI)
Ctrl + I - to create my raid.
Using the internal floppy disk drive, i loaded a floppy disk with the F6 drivers in it.
Insert my OS installation disk and press F6, followed by S to specify the location of the drive.
Continue the OS installation.
Using Nlite to slipstream the F6 drivers thus creating a new OS CD with the drivers already embedded.
That's all. It worked fine 100%.
